Title: Fabrication of devices using phosphorus glasses
Inventor: EKHOLM DAVID T
IPC: H01L21/285
Filed: 1987-06-19
Granted: 1993-12-07
Abstract: A fabrication technique is described for making various devices in which a type of glass is used as a surface protection layer. The glass layers are put down by particle bombardment (generally sputtering or e-beam bombardment) of a phosphorus-containing silicate glass target. <Devices with such layers are also described.> Such glass layers are highly advantageous as encapsulating material, diffusion barrier layers, etc., particularly for optical type devices and certain semiconductor devices. Particularly important is the preparation procedure for the glass target used in the bombardment process. The glass layers are moisture stable, act as excellent barriers against diffusion, and are usable up to quite high temperatures without cracking or peeling. The glass layers also provide longterm protection against atmosphere components including water vapor, oxygen, atmosphere pollution contaminants, etc.

Title: Dust suppressant forming a resilient layer
Inventor: KREMER HENRY A
IPC: C09D195/00

Granted: 1993-01-19
Abstract: ABSTRACT OF DISCLOSURE      A DUST SUPPRESSANT FORMING A RESILIENT LAYER    A dust suppressant forming a resilient layer penet-rating dusting materials.  This suppressant comprises at least 45% water.  A water thickening agent is dissolved in water, and forms with water the dispersion medium.  A coal tar pitch is dissolved in an aromatic solvent and forms the dispersed liquid which results in suspension.  The aromatic solvent has generally a residual softening point of about 40-70°C (as measured by ASTM-D-36), and forms the dispersed liquid which results in the suspension.  This dust suppressant has a viscosity of 3500 to 15000 cps at 25°C.          A process for making same comprises: 1- adding to water having a pH of about 7 to 9, a thickening agent to form a dispersion medium having a viscosity of at least 2000 centipoises at 25°C as measured with ASTM-D4420, with a Brookfield, 2- dispensing under high shear conditions into said dispersion medium, a pitch dissolved in an aromatic solvent, at least 70% of which is boiling over 270°C, said aromatic solvent being substantially the solvent agent of said pitch and preferably consisting of anthracene oil, to obtain a suspension (in concentrate form) having at least 45% water content.  A process is also contemplated which includes diluting a suspension in concentrate form to obtain a diluted suspension having 90-98% water content by weight, and 2-10% by weight of said suspension in concentrate form, and directly spraying said diluted suspension at the rate 10-40 grams of solids per metric ton of dusting material.

Title: Multiprocessing method and arrangement
Inventor: SCHAN EDWARD P JR
IPC: G06F9/46
Filed: 1988-01-29
Granted: 1992-03-24
Abstract: Abstract A master-slave multiprocessor is formed by connecting a slave processor to an I/O slot of a uniprocessor, and minimally modifying the uniprocessor's operating system. At initialization, one routine redirects slave interrupt vectors to point to a common interrupt handler. Before a process executes on the slave processor, another routine corrupts execution stack bounds of the process. A non-interrupt operating system call during execution of the process causes an automatic firmware check of the execution stack pointer against the stack bounds. Occurrence of an interrupt or encounter of a stack exception results in suspension of process execution and invocation of the interrupt handler or a slave stack exception handler, respectively. Each handler calls a slave delete routine to restore the process' stack bounds to valid values and to transfer process for execution to the master processor. On the master processor, process execution resumes at the point of suspension, and the operating system service required by the system call or interrupt is carried out.

Abstract: A novel interferometer and method of determining incremental movement are provided herein.   The interferometer includes a source of a laser beam of radiant energy;  a beam splitter disposed across the path of the beam of radiant energy for splitting the beam into reflected beams and transmitted beams; a reflector for receiving or reflecting a beam of radiant energy which has been reflected by the beam splitter;  an optical recording device disposed in the path of a beam reflected by the beam splitter; a rigid cantilevered arm having a coating thereon whose incremental movement is to be measured; and a mirror, mounted on the cantilevered arm, for reflecting a beam of radiant energy reflected by the beam splitter.  The incremental movement is measured by a determination of the movement of an interference pattern produced by interference of the two beams of the radiant energy.  The interferometer is capable of measuring a deflection of at least 1/20th of a wave-length of light (?300.ANG. or 30 nm) in an arm,  e.g. of stainless steel, with the sensitivity being dependent on the size of the steel arm.   A long steel arm increases the sensitivity, while a thicker steel arm decreases it.

Abstract: ABSTRACT             Injection Moulding Apparatus Apparatus for producing an injection moulding of plastics material comprises means for introducing a supply of plastics material through one or more openings in a mould space, and means for introducing a pressurised gas through a separate opening in the mould space into the plastics material filling the mould space whereby the gas creates a gas containing cavity in the plastics material and for thereafter relieving the gas pressure within the gas containing cavity before the mould is opened.  The gas supply/pressure relieving means comprise at said separate opening a valve port opening directly into the mould space, a valve member for opening and closing the valve port, and means to supply pressurised gas to the mould space.  The gas supply means are arranged to supply gas through the valve member whilst the valve member is in a valve port closed position to create the cavity and after a moulding operation has been finished, the supply of pressurised gas can be terminated and pressurised gas in the cavity in the moulding can be vented to the atmosphere due to movement of the valve member to a valve port open position.

Abstract: PLASMA THIN FILM DEPOSITION PROCESS CONTROL               Abstract of the Disclosure In a process of depositing a thin film onto a surface of a substrate with the use of a plasma, wherein the plasma optical emission is monitored, analyzed, and the results used to automatically control the nature of the plasma in order to control the characteristics of the deposited thin film.  One aspect of the emission that is detected is the intensity of each of two emission lines of different wavelength bands from the same plasma species, the intensities being ratioed and the ratio compared to a predetermined value known to provide a resulting film with uniform and repeatable characteristics.  This ratio is also related to the average electron temperature of the plasma, which can be calculated from it.  Additionally, the intensity of another emission line from another of the plasma species may be measured and ratioed to one of the foregoing  line  intensifies  if  additional  control  is desired.
